Paleomagnetism is the study of the terrestrial magnetic field during rocks formation or geological processes. The correct option is D. <em>The study of the </em><em>magnetic qualities </em><em>of </em><em>ancient rocks.</em>
-----------------------------
Paleomagnetism is a branch of geology, and refers to the study of the terrestrial magnetic field registered at the moment of a rock formation or during subsequent relevant geological processes, such as metamorphism.
It is based on three basic assumptions:
- Axial geocentric dipole
- Record of the primary magnetic field
- Invariable record in time
The paleomagnetic analysis includes a series of control tools used to verify que acomplishments of these assumptions in the study area.
The correct option would be option <em>D. The study of the </em><em>magnetic qualities </em><em>of </em><em>ancient rocks.</em>

Answer:
a.i and iii are correct
Explanation:
Biology is the study of the living organism and how they interact with the other components of the environment and among eachother, this is very important because then you can make the inference that biology studies energy as long as it is carried out by organisms and in the cain et al the definition of environment is the abiotic, or non living organisms with which the living organisms interact.
Answer:
lol what?
Explanation:
A base pair is two chemical bases bonded to one another forming a "rung of the DNA ladder." The DNA molecule consists of two strands that wind around each other like a twisted ladder. Each strand has a backbone made of alternating sugar (deoxyribose) and phosphate groups. Attached to each sugar is one of four bases--adenine (A), cytosine (C), guanine (G), or thymine (T). The two strands are held together by hydrogen bonds between the bases, with adenine forming a base pair with thymine, and cytosine forming a base pair with guanine.
Answer:
The X-shaped structure is made of strands of DNA.
Explanation:
The chromosomes are thread-like structures located in the nucleus of each cell in the body. In a human cell, there are 23 pairs of chromosomes found in the nucleus. Each chromosome is made up of strands of DNA tightly coiled many times around proteins called histones which gives support to its structure.
The chromosomes are X-shaped and are observed only in a cell undergoing division by mitosis or meiosis. Each of these X-shaped chromosomes consists of two identical sister chromatids. The sister chromatids are connected to each other by a region of the chromosome called the centromere. The centromere are located around the depression point of the chromosome which divides the sister chromatids into two regions: long arm called the q arm and a shorter arm called the p arm. During mitosis, spindle fibers attach to this region, and they eventually pull the sister chromatids apart to form two separate chromosomes, one for each daughter cell.
